Changed over to 69 single caliper style ft's. New mntg brkt's, caliper's, rotors's, and hoses. After applying and releasing pedal, RH rotor will barely turn. Repeted a few times. LH side works great. Caliper sits alittle different then LH side. Possible bad "new" mntg brkt. Knuckle looks fine? Any thoughts or ideas before i try another caliper. I'm leary of the 67-8's 4 piston combo valve system.
